Hi Steve , Hi Joe and all
A few more details following some furthers tests today :
1/ T0 : start application enable TX ticked (red) ( nothing else touch ie
no modification of Tx% at 20% )
2/ T0+1h : Happily decoding but no TX
3/T0+2h : same status
4/T0+2h10mn : press TX next , one TX cycle and then no further TX
5/T0+3H : still no further TX
6/T0+3H20 : Change TX & at 25 %
7/ As at still no Tx the press TX_next (09h48) and then process started
:-)
8/ Now more than 2 hours later still running happily for how long … but
so far so good ! ?
You will find screenshots and log files at dropbox below .

My conclusion so far is that to ensure start of the scheduler : Press enable
TX , followed by a change of percentage AND then a TX next is required !
Once started will it stop? I do not know (yet) but it has been running more
than two hours now ! :-)
I may try to have look at code :WsprTxScheduler, WSPR BandHopping and
mainwindows I assume , but I am sure you will be more efficient to correlate it
with above . ( I am much more a C microcontroller man or financial market
more than a QT expert :-) )
Very best regards
Jean Louis
Test environment : Windows 8.1 , WSJT-X r 5685 , FT897
Summary to Steve's questions :
Does this happen only if you have never touched TX Pct since starting the
program?
>Yes
When you observed this behavior what was the TX Pct?
>20 %
How long did you run with no transmissions?
>More than 2 Hours
In particular, did you go for a full 2 hours with no transmission?
>Yes
If so, then does the scheduler eventually kick in after 2 hours with no
transmission?
>Only triggered by a TxNext AND a change of %

Jean Louis, Joe -
Does this happen only if you have never touched TX Pct since starting the
program?
When you observed this behavior what was the TX Pct? How long did you run with
no transmissions? In particular, did you go for a full 2 hours with no
transmission? If so, then does the scheduler eventually kick in after 2 hours
with no transmission?
I haven’t changed anything in the wspr tx scheduler recently. I know that Bill
adjusted the band selection algorithm not too long ago, but that shouldn’t have
involved the scheduler. I just looked at the code, and it seems that the tx
table should be automatically generated the first time that next_tx_state() is
called.
I’ll also note that the statistics of the scheduler may “feel” different when
TX Pct is less than 17%, as a different algorithm is used in that regime.
